I think following atkins is only sensible for you on lifetime maintenence. You should concentrate on eating really healthy foods and not all the artificial low carb substitutes you have been eating - they aren't that great for you. Your current stats indicate that you would be extremely lean and do not need to lose anymore weight. I know that when i was 14 i had problems with weight and always thought i was overweight even though i was 110 ~ 5"7 - i look back now and think yuck did i really look like that!!!! You just need to concentrate on being healthy
